Using client and SDK ver 4.5.14.34698. Previously had no issues with TT, but now launching it via the Tools menu pops up the Traffic Explorer box with a white background and a sim hang. After approximately ten seconds the current user aircraft appears at the top of the list, then the sim CTD's.
I've verified all the paths are current, and uninstalled/reinstalled to no avail. Is this a known issue in the latest 4.5 version?
